Well, it's Wednesday, and you know what that means... IBM Announcements!</p>
<blockquote>
(Actually most IBM announcements are on Tuesdays, but IBM gave me extra time to recover from my trip to Europe!)
</blockquote>
<p>
Today, IBM announced [<a href="http://www.ibm.com/puresystems">IBM PureSystems</a>], a new family of expert-integrated systems that combine storage, servers, networking, and software, based on IBM's decades of experience in the IT industry. You can register for the [<a href="http://bit.ly/IATuqQ">Launch Event</a>] today (April 11) at 2pm EDT, and download the companion &quot;Integrated Expertise&quot; event app for Apple, Android or Blackberry smartphones.

<blockquote>
(If you are thinking, <i>&quot;Hey, wait a minute, hasn't this been done before?&quot;</i> you are not alone. Yes, IBM introduced the System/360 back in 1964, and the AS/400 back in 1988, so today's announcement is on scheduled for this 24-year cycle. Based on IBM's past success in this area, others have followed, most recently, Oracle, HP and Cisco.)
</blockquote>
<p>
Initially, there are two offerings:
</p>
<dl>
<dt><b>IBM PureFlex™ System</b></dt>
<dd><p>
IBM PureFlex is like IaaS-in-a-box, allowing you to manage the system as a pool of virtual resources. It can be used for private cloud deployments, hybrid cloud deployments, or by service providers to offer public cloud solutions. IBM drinks its own champagne, and will have no problem integrating these into its [<a href="http://www.ibm.com/cloud-computing/us/en/">IBM SmartCloud</a>] offerings.
</p>
<p>
To simplify ordering, the IBM PureFlex comes in three <i>tee-shirt</i> sizes: Express, Standard and Enterprise.
</p>
<p>
IBM PureFlex is based on a 10U-high, 19-inch wide, standard rack-mountable chassis that holds 14 bays, organized in a 7 by 2 matrix. Unlike BladeCenter where blades are inserted vertically, the IBM PureFlex nodes are horizontal. Some of the nodes take up a single bay (half-wide), but a few are full-wide, take up two bays, the full 19-inch width of the chassis. Compute and storage snap in the front, while power supplies, fans, and networking snap in the back. You can fit up to four chassis in a standard 42U rack.</p>
<p>
Unlike competitive offerings, IBM does not limit you to x86 architectures. Both x86 and POWER-based compute nodes can be mixed into a single chassis. Out of the box, the IBM PureFlex supports four operating systems (AIX, IBM i, Linux and Windows), four server hypervisors (Hyper-V, Linux KVM, PowerVM, and VMware), and two storage hypervisors (SAN Volume Controller and Storwize V7000).</p>
<p>
There are a variety of storage options for this. IBM will offer SSD and HDD inside the compute nodes themselves, direct-attached storage nodes, and an integrated version of the Storwize V7000 disk system. Of course, every IBM System Storage product is supported as external storage. Since Storwize V7000 and SAN Volume Controller support external virtualization, many non-IBM devices will be supported automatically as well.</p>
<p>
Networking is also optimized, with options for 10Gb and 40Gb Ethernet/FCoE, 40Gb and 56Gb Infiniband, 8Gbps and 16Gbps Fibre Channel. Much of the networking traffic can be handled within the chassis, to minimize traffic on external switches and directors.</p>
<p>
For management, IBM offers the Flex System Manager, that allows you to manage all the resources from a single pane of glass. The goal is to greatly simplify the IT lifecycle experience of procurement, installation, deployment and maintenance.
</p></dd>
<dt><b>IBM PureApplication™ System</b></dt>
<dd><p>
IBM PureApplication is like PaaS-in-a-box. Based on the IBM PureFlex infrastructure, the IBM PureApplication adds additional software layers focused on transactional web, business logic, and database workloads. Initially, it will offer two platforms: Linux platform based on x86 processors, Linux KVM and Red Hat Enterprise Linux (RHEL); and a UNIX platform based on POWER7 processors, PowerVM and AIX operating system. It will be offered in four tee-shirt sizes (small, medium, large and extra large).</p>
<p>
In addition to having IBM's middleware like DB2 and WebSphere optimized for this platform, over 600 companies will announce this week that they will support and participate in the IBM PureSystems ecosystem as well. Already, there are 150 "Patterns of Expertise" ready to deploy from IBM PureSystem Centre, a kind of a &quot;data center app store&quot;, borrowing an idea used today with smartphones.</p>
<p>
By packaging applications in this manner, workloads can easily shift between private, hybrid and public clouds.

<p>
Have you ever noticed that sometimes two movies come out that seem eerily similar to each other, released by different studios within months or weeks of each other? My sister used to review film scripts for a living, she would read ten of them and have to pick her top three favorites, and tells me that scripts for nearly identical concepts came all the time. Here are a few of my favorite examples:
</p>
<ul>
<li>1994: [<a href="http://www.imdb.com/title/tt0111756/">Wyatt Earp</a>] and [<a href="http://www.imdb.com/title/tt0108358/">Tombstone</a>] were Westerns recounting the famed gunfight at the O.K. Corral. Tombstone, Arizona is near Tucson, and the gunfight is recreated fairly often for tourists.
</li><li>1998: [<a href="http://www.imdb.com/title/tt0120591/">Armageddon</a>] and [<a href="http://www.imdb.com/title/tt0120647/">Deep Impact</a>] were a pair of disaster movies dealing with a large rock heading to destroy all life on earth. I was in Mazatlan, Mexico to see the latter, dubbed in Spanish as &quot;Impacto Profundo&quot;.
</li><li>1998: [<a href="http://www.imdb.com/title/tt0120623/">A Bug's Life</a>] and [<a href="http://www.imdb.com/title/tt0120587/">Antz</a>] were computer-animated tales of the struggle of one individual ant in an ant colony.
</li><li>2000: [<a href="http://www.imdb.com/title/tt0183523/">Mission to Mars</a>] and [<a href="http://www.imdb.com/title/tt0199753/">Red Planet</a>] were sci-fi pics exploring what a manned mission to our neighboring planet might entail.
</li><li>2009: [<a href="http://www.imdb.com/title/tt1114740/">Paul Blart: Mall Cop</a>] and [<a href="http://www.imdb.com/title/tt1197628/">Observe and Report</a>] were comedies dealing with challenges of security at a shopping mall.
</li></ul>
<blockquote>
(I think I made my point with just a few examples. A more complete list can be found on [<a href="http://www.11points.com/Movies/11_Damn_Near_Identical_Movies_That_Were_Released_at_the_Same_Time">Sam Greenspan's 11 Points website</a>].)
</blockquote>
<p>
This is different than copy-cat movies that are re-made or re-imagined many years later based on the previous successes of an original. Ever since my blog post [<a href="https://www.ibm.com/developerworks/mydeveloperworks/blogs/InsideSystemStorage/entry/vplex_emc_s_latest_wheel_is_round6?lang=en">VPLEX: EMC's Latest Wheel is Round</a>] in 2010 comparing EMC's copy-cat product that came our <u>seven years</u> after IBM's SAN Volume Controller (SVC), I've noticed EMC doesn't talk about VPLEX that much anymore.</p>
<p>
This week, IBM announced [<a href="https://www.ibm.com/developerworks/mydeveloperworks/blogs/InsideSystemStorage/entry/ibm_announcements_for_february_20128?lang=en">XIV Gen3 Solid-State Drive support</a>] and our friends over at EMC announced [<a href="http://www.emc.com/about/news/press/2012/20120206-01.htm">VFCache SSD-based PCIe cards</a>]. Neither of these should be a surprise to anyone who follows the IT industry, as IBM had announced its XIV Gen3 as &quot;SSD-Ready&quot; last year specifically for this purpose, and EMC has been touting its &quot;Project Lightning&quot; since last May.</p>
<p>
Fellow blogger Chris Mellor from <i>The Register</i> has a series of articles to cover this, including [<a href="http://www.theregister.co.uk/2012/02/06/emc_vfcache/">EMC crashes the server flash party</a>], [<a href="http://www.theregister.co.uk/2012/02/07/netapp_lightning_answer/">NetApp slaps down Lightning with multi-card Flash flush</a>], [<a href="http://www.channelregister.co.uk/2012/02/08/hp_gen8_flash/">HP may be going the server flash route</a>], and [<a href="http://www.theregister.co.uk/2012/02/08/hds_lightning/">Now HDS joins the server flash party</a>].
</p>
<p>
Fellow blogger Chuck Hollis from EMC has a blog post [<a href="http://chucksblog.emc.com/chucks_blog/2012/02/vfcache-means-very-fast-cache-indeed.html?utm_source=feedburner&amp;utm_medium=feed&amp;utm_campaign=Feed%3A+emc%2FYkrh+%28Chuck%27s+Blog%29&amp;utm_content=Google+Reader">VFCache means Very Fast Cache indeed</a>] that provides additional detail. Chuck claims the VFCache is faster than popular [<a href="http://www-03.ibm.com/systems/info/x86servers/serverproven/compat/us/serverproven/fusioniob.shtml">Fusion-IO PCIe cards</a>] available for IBM servers. I haven't seen the performance spec sheets, but typically SSD is four to five times slower than the DRAM cache used in the XIV Gen3. The VFCache's SSD is probably similar in performance to the SSD supported in the IBM XIV Gen3, DS8000, DS5000, SVC, N series, and Storwize V7000 disk systems.
</p>
<p>
Nonetheless, I've been asked my opinions on the comparison between these two announcements, as they both deal with improving application performance through the use of Solid-State Drives as an added layer of read cache.
</p>

</blockquote>
<p>
The solutions are different in that IBM XIV Gen3 the SSD is &quot;storage-side&quot; in the external storage device, and EMC VFCache is &quot;server-side&quot; as a PCI Express [<a href="http://en.wikipedia.org/wiki/PCI_Express">PCIe</a>] card. Aside from that, both implement SSD as an additional read cache layer in front of spinning disk to boost performance. Neither is an industry first, as IBM has offered server-side SSD since 2007, and IBM and EMC have offered storage-side SSD in many of their other external storage devices. The use of SSD as read cache has already been available in IBM N series using [<a href="http://www-03.ibm.com/systems/storage/network/software/pam/">Performance Accelerator Module (PAM)</a>] cards.</p>
<p>
IBM has offered cooperative caching synergy between its servers and its storage arrays for some time now. The predecessor to today's POWER7-based were the iSeries i5 servers that used PCI-X IOP cards with cache to connect i5/OS applications to IBM's external disk and tape systems. To compete in this space, EMC created their own PCI-X cards to attach their own disk systems. In 2006, IBM did the right thing for our clients and fostered competition by entering in a [<a href="http://www.itjungle.com/tfh/tfh050310-story03.html">Landmark agreement</a>] with EMC to [<a href="http://www.itjungle.com/tfh/tfh032706-story02.html">license the i5 interfaces</a>]. Today, VIOS on IBM POWER systems allows a much broader choice of disk options for IBM i clients, including the IBM SVC, Storwize V7000 and XIV storage systems.
</p>
<p>
EMC is not the first to manufacture an SSD-based PCIe card. Last summer, my friends at Texas Memory Systems [<a href="http://www.ramsan.com/">TMS</a>] gave away a [<a href="http://www.ramsan.com/products/pcie-storage/ramsan-70">RAMsan-70 PCIe card</a>] at an after-party on [<a href="https://www.ibm.com/developerworks/mydeveloperworks/blogs/InsideSystemStorage/entry/ibmtechu_day_2_ibm_storage_university_solutions_expo4?lang=en">Day 2 of the IBM System Storage University</a>].
</p>
<p>
Can a little SSD really help performance? Yes! An IBM client running a [<a href="http://www-01.ibm.com/software/data/db2/">DB2 Universal Database</a>] cluster across eight System x servers was able to replace an 800-drive EMC Symmetrix by putting eight SSD Fusion-IO cards in each server, for a total of 64 Solid-State drives, saving money and improving performance. DB2 has the Data Partitioning Feature that has multi-system DB2 configurations using a Grid-like architecture similar to how XIV is designed. Most IBM System x and BladeCenter servers support internal SSD storage options, and many offer PCIe slots for third-party SSD cards. Sadly, you can't do this with a VFCache card, since you can have only one VFCache card in each server, the data is unprotected, and only for ephemeral data like transaction logs or other temporary data. With multiple Fusion-IO cards in an IBM server, you can configure a RAID rank across the SSD, and use it for persistent storage like DB2 databases.
</p>
<p>
Here then is my side-by-side comparison:
</p>

<tr><td>Protocol support</td><td bgcolor="#ffff33">FCP</td><td bgcolor="#00ff33">FCP and iSCSI</td></tr>
<tr><td>Vendor-supplied driver required on the server</td><td bgcolor="#ffff33">Yes, the VFCache driver must be installed to use this feature.</td><td bgcolor="#00ff33">No, IBM XIV Gen3 uses native OS-based multi-pathing drivers.</td></tr>
<tr><td>External disk storage systems required</td><td bgcolor="#00ff33">None, it appears the VFCache has no direct interaction with the back-end disk array, so in theory the benefits are the same whether you use this VFCache card in front of EMC storage or IBM storage</td><td bgcolor="#ffff33">XIV Gen3 is required, as the SSD slots are not available on older models of IBM XIV.</td></tr>
<tr><td>Shared disk support</td><td bgcolor="#ffff33">No, VFCache has to be disabled and removed for vMotion to take place.</td><td bgcolor="#00ff33">Yes! XIV Gen3 SSD caching shared disk supports VMware vMotion and Live Partition Mobility.</td></tr>
<tr><td>Support for multiple servers</td><td bgcolor="#ffff33">No</td><td bgcolor="#00ff33">An advantage of the XIV Gen3 SSD caching approach is that the cache can be dynamically allocated to the busiest data from any server or servers.</td></tr>
<tr><td>Support for active/active server clusters</td><td bgcolor="#ffff33">No</td><td bgcolor="#00ff33">Yes!</td></tr>
<tr><td>Aware of changes made to back-end disk</td><td bgcolor="#ffff33">No, it appears the VFCache has no direct interaction with the back-end disk array, so any changes to the data on the box itself are not communicated back to the VFCache card itself to invalidate the cache contents.</td><td bgcolor="#00ff33">Yes!</td></tr>
<tr><td>Sequential-access detection</td><td bgcolor="#ffff33">None identified. However, VFCache only caches blocks 64KB or smaller, so any sequential processing with larger blocks will bypass the VFCache.</td><td bgcolor="#00ff33">Yes! XIV algorithms detect sequential access and avoid polluting the SSD with these blocks of data.</td></tr>
<tr><td>Number of SSD supported</td><td bgcolor="#ffff33">One, which seems odd as IBM supports multiple Fusion-IO cards for its servers. However, this is not really a single point of failure (SPOF) as an application experiencing a VFCache failure merely drops down to external disk array speed, no data is lost since it is only read cache.</td><td bgcolor="#00ff33">6 to 15 (one per XIV module) for high availability.</td></tr>
<tr><td>Pin data in SSD cache</td><td bgcolor="#00ff33">Yes, using split-card mode, you can designate a portion of the 300GB to serve as Direct-attached storage (DAS). All data written to the DAS portion will be kept in SSD. However, since only one card is supported per server and the data is unprotected, this should only be used for ephemeral data like logs and temp files.</td><td bgcolor="#ffff33">No, there is no option to designate an XIV Gen3 volume to be SSD-only. Consider using Fusion-IO PCIe card as a DAS alternative, or another IBM storage system for that requirement.</td></tr>
<tr><td>Hot-pluggable/Hot-swappable</td><td bgcolor="#ffff33">Not identified</td><td bgcolor="#00ff33">Yes!</td></tr>
<tr><td>Pre-sales Estimating tools</td><td bgcolor="#ffff33">None identified</td><td bgcolor="#00ff33">Yes! <i>CDF</i> and <i>Disk Magic</i> tools are available to help cost-justify the purchase of SSD based on workload performance analysis.</td></tr>
</tbody></table>
<p>
IBM has the advantage that it designs and manufactures both servers <u>and</u> storage, and can design optimal solutions for our clients in that regard.
